Abstract:
      The anti-fatigue effects of corn peptide glycosylated by chitosan (corn glycopeptide) were evaluated through the weight-loaded swimming test and the detection of biochemical indexes related to fatigue. The results showed that compared with the 500 mg/kg corn peptide group, the corn glycopeptide had more significant effect of delaying fatigue. Compared with the model group, the corn glycopeptide group at 500 mg/kg dose increased the weight loading swimming time by 92.59%, the contents of blood serum lactate, blood serum urea nitrogen, and liver malondialdehyde were reduced by 15.67%, 1327%, 4199% and 25.53%, respectively, and the contents of muscle glycogen, liver glycogen and glutathione and activity of superoxide dismutase increased by 54.41%, 398.90%, 182.76% and 9439%, respectively. Corn glycopeptide has great market potential as anatural anti-fatigue food.
